tank to small for a dovii, need a 300g for them, at 12" they will kill anything in the tank. These guys eat all other cichlids in the wild, they are the top of the food chain. and they get big.
Well, I'm doing the 90 for a while for him. He's at about 9" now, and seems cool so far. May think about a 120 down the road, but a 180? or 300? nah.....ain't happening. When i was a kid a 55 was considered huge! Now a 55 g. is small!? Don't get it??
